The Woodstock Music & Art Fair—informally, the Woodstock Festival or simply Woodstock—was a music festival attracting an audience of over 400,000 people, scheduled over three days on a dairy farm in New York state from August 15 to 17, 1969, but ultimately ran four days long, ending August 18, 1969.

Billed as "An Aquarian Exposition: 3 Days of Peace & Music", it was held at Max Yasgur's 600-acre (240 ha; 0.94 sq mi) dairy farm in the Catskills near the hamlet of White Lake in the town of Bethel. Bethel, in Sullivan County, is 43 miles (69 km) southwest of the town of Woodstock, New York, in adjoining Ulster County.
